[0035] Please refer to Figures 1 to 7The embodiment of the utility model discloses a charger for hidden pin storage, which comprises: a housing 1 and a pin 2, wherein the housing 1 is provided with a hidden groove 11 for storing the pin 2, and the housing 1 is provided with a rotating shaft 41 near one end of the hidden groove 11, and one end of the pin 2 extends into the hidden groove 11 and is connected to the rotating shaft 41; wherein elastic members 42 are respectively provided at both ends of the rotating shaft 41, and the elastic members 42 are used to provide elastic force so that the rotating shaft 41 rotates to drive the other end of the pin 2 to rotate out of the hidden groove 11; and an eject button is provided on the housing 1. 3. An unlocking lever 43 and a locking member 44 are provided in the housing 1. The locking member 44 is used to limit the rotation of the rotating shaft 41 so that the pin 2 remains stored in the hidden groove 11. The unlocking lever 43 is connected between the locking member 44 and the ejection button 3. When the ejection button 3 is pressed, the ejection button 3 drives the unlocking lever 43 to rotate, and the unlocking lever 43 drives the locking member 44 to move. The locking member 44 releases the rotation limit of the rotating shaft 41, and the elastic member 42 drives the rotating shaft 41 to rotate so that the other end of the pin 2 rotates out of the hidden groove 11. Specifically, the elastic member 42 is a torsion spring.

[0036] It is understandable that the elastic member 42 (such as a torsion spring) in the above embodiment is used to store and release energy. When the pin 2 is received in the hidden groove 11, the rotation axis 41 is limited by the locking member 44, and the elastic member 42 is in a compressed or twisted state, storing energy. When the rotation limit of the locking member 44 on the rotation axis 41 is released, the elastic member 42 releases energy, drives the rotation axis 41 to rotate, and the other end of the pin 2 is automatically ejected. Furthermore, the unlocking lever 43 uses the lever principle to realize the transmission effect, and transmits the force of pressing the ejection button 3 to the locking member 44, realizing the unlocking action of the locking member 44. Specifically, during the pop-up process of a pin 2, the initial state is that the pin 2 is completely received in the hidden groove 11 of the shell 1, the elastic members 42 at both ends of the rotating shaft 41 are in a compressed or torsion state, and the locking member 44 limits the rotation of the rotating shaft 41; when the user presses the pop-up button 3 on the shell 1, the force of the pop-up button 3 is transmitted to the locking member 44 through the unlocking lever 43 and drives the locking member 44 to move, thereby releasing the rotation limit of the rotating shaft 41 by the locking member 44; as the locking member 44 is unlocked, the elastic member 42 releases the stored energy, drives the rotating shaft 41 to rotate, thereby driving the other end of the pin 2 to rotate out of the hidden groove 11, and realizing the automatic pop-up of the pin 2.

[0037] Further, for modular design and facilitating the maintenance and replacement of components, an installation seat 4 is provided in the housing 1 of this embodiment. The rotating shaft 41, the elastic member 42, the unlocking lever 43, and the locking member 44 are all arranged on the installation seat 4. The installation seat 4 is detachably connected to the housing 1. By integrating the rotating shaft 41, the elastic member 42, the unlocking lever 43, and the locking member 44 on one installation seat 4 to form an independent module, and adopting a detachable connection (such as screws, buckles, etc.) between the installation seat 4 and the housing 1, the module can be conveniently detached from the housing 1, and the components on the installation seat 4 can be repaired or replaced separately. After the repair or replacement is completed, the installation seat 4 can be reinstalled on the housing 1.

[0038] Further, to ensure that the plug pin 2 can be stably received in the hidden groove 11 when not in use, prevent it from accidentally popping out, and at the same time can quickly and stably automatically pop out when needed. Therefore, in this embodiment, a matching structure between the European locking member 44 and the rotating shaft 41 is proposed to stably execute the receiving function and the popping function of the charger for the plug pin 2. In this embodiment, a contact projection 411 is provided on the rotating shaft 41. The middle part of the locking member 44 is rotatably connected to the installation seat 4. One end of the locking member 44 is connected to the unlocking lever 43, and the other end is close to the rotating shaft 41. When the plug pin 2 is received in the hidden groove 11, the other end of the locking member 44 abuts against the contact projection 411 to limit the rotation of the rotating shaft 41 in the direction of rotating the other end of the plug pin 2 out. When the pop-up button 3 is pressed, the unlocking lever 43 drives the locking member 44 to rotate, so that the other end of the locking member 44 moves away from the contact projection 411 to release the rotation limit of the rotating shaft 41. Through the cooperation between the locking member 44 and the contact projection 411, the stability of the plug pin 2 when received in the hidden groove 11 is ensured, and its accidental popping out is prevented. The user can quickly release the locked state and realize the automatic pop-up of the plug pin 2 only by pressing the simple action of the pop-up button 3, which greatly improves the convenience of use.

[0039] Further, the middle part of the unlocking lever 43 is rotatably connected to the mounting base 4. One end of the unlocking lever 43 is connected to the eject button 3, and the other end is connected to one end of the locking member 44. It can be understood that the unlocking lever 43 serves as a mechanical lever, and its middle part is rotatably connected to the mounting base 4 to form a fulcrum. When the user presses the eject button 3, the force is transmitted through one end of the unlocking lever 43, and the other end acts on the locking member 44 to change the direction of the force. Further, the locking member 44 in this embodiment can also be regarded as a lever. By receiving the acting force from the other end of the unlocking lever 43 at one end, its position is changed, resulting in a change in the relative position between its other end and the abutting protrusion 411, thereby releasing the rotational limit on the rotating shaft 41. It should be explained that when the pin 2 is received in the hidden groove 11, the unlocking lever 43 remains in a balanced position, with one end connected to the eject button 3 and the other end connected to the locking member 44, but does not apply enough force to cause it to rotate. When the user presses the eject button 3, the eject button 3 pushes one end of the unlocking lever 43 downward. Since the middle part of the unlocking lever 43 is rotatably connected to the mounting base 4 to form a fulcrum, the unlocking lever 43 will rotate around its fulcrum. As the unlocking lever 43 rotates, its other end will push the locking member 44, causing the other end of the locking member 44 to leave the abutting protrusion 411 and releasing the rotational restriction on the rotating shaft 41.

[0040] Specifically, the eject button 3 is located above one end of the unlocking lever 43, and the other end of the unlocking lever 43 is located below one end of the locking member 44.

[0041] Specifically, a charging circuit is further provided in the housing 1, and one end of the pin 2 is electrically connected to the charging circuit.

[0042] In one embodiment, a wire accommodating groove 12 is further provided on the housing 1. A connection hole 14 is provided at one end of the wire accommodating groove 12, and a plug accommodating groove 13 is provided at the other end. A charging wire 5 is provided in the wire accommodating groove 12. The charging wire 5 includes a wire body 51 and a plug 52. The plug 52 is connected to one end of the wire body 51. The wire body 51 is located in the wire accommodating groove 12. The plug 52 is detachably connected to the plug accommodating groove 13. The other end of the wire body 51 passes through the connection hole 14 and is electrically connected to the charging circuit. When the user needs to use the charger to charge, the charging wire 5 can be pulled out from the wire accommodating groove 12, and the plug 52 is inserted into the device to be charged. At this time, the charging circuit starts to work, and electric energy is transmitted to the device through the wire body 51. When the charging is completed, the user can pull out the plug 52 from the device, squeeze the wire body 51 into the wire accommodating groove 12, and put the plug 52 into the plug accommodating groove 13 to realize the storage of the charging wire 5. By integrating the housing 1 and the charging wire 5 into a whole, the charger is more convenient to carry, reducing the risk of forgetting to carry the charging wire 5. The charging wire 5 can be neatly stored in the wire accommodating groove 12, avoiding the winding problem after long-term carrying and use. The plug 52 can be stored in the plug accommodating groove 13, avoiding the risk of being polluted or damaged when exposed to the external environment during non-use.

[0043] Further, a first connecting member 131 is provided in the plug accommodating groove 13, and a second connecting member is provided on the plug 52. The first connecting member 131 and the second connecting member are magnetically connected. It can be understood that in this embodiment, the magnetic connection principle is adopted. When the plug 52 is stored in the plug accommodating groove 13, the first connecting member 131 and the second connecting member are attracted to each other by magnetic force, realizing the stable connection and fixation of the plug 52. After the charging is completed, the user pulls the plug 52 out of the charging device and brings the plug 52 close to the plug accommodating groove 13. Due to the magnetic attraction between the first connecting member 131 and the second connecting member, the plug 52 will be automatically adsorbed into the plug accommodating groove 13. After the plug 52 is completely stored in the plug accommodating groove 13, the magnetic force between the first connecting member 131 and the second connecting member ensures that the plug 52 is firmly fixed in the groove and is not easy to fall off or shake. When the user needs to use the charger again, just gently pull the plug 52 to overcome the magnetic attraction, and the plug 52 can be taken out from the plug accommodating groove 13.

[0044] Specifically, both the first connecting member 131 and the second connecting member are magnets; or one of the first connecting member 131 and the second connecting member is a magnet, and the other is an iron sheet. It can be understood that a magnet has the property of attracting magnetic materials such as iron, nickel, and cobalt. When two magnets or a magnet and an iron sheet are close to each other, an attractive force will be generated between them. Using a combination of magnets or a magnet and an iron sheet can ensure a more stable and reliable connection between the plug 52 and the plug accommodating groove 13, avoiding shaking or falling off during carrying or storage.

[0045] Further, an elastic switch 132 is provided at the bottom of the plug receiving groove 13 in the insertion direction of the plug 52. The elastic switch 132 has a first state and a second state. When the plug 52 abuts against and presses the elastic switch 132, the elastic switch 132 switches from the first state to the second state, or from the second state to the first state; when the elastic switch 132 is in the first state, the second connecting member approaches the first connecting member 131 so that the first connecting member 131 and the second connecting member are magnetically attracted and connected; when the elastic switch 132 is in the second state, the second connecting member moves away from the first connecting member 131 so that the portion of the plug 52 close to the wire body 51 passes through the plug receiving groove 13 and is exposed. Specifically, the first connecting member 131 is provided at the bottom of the plug receiving groove 13 in the insertion direction of the plug 52.

[0046] It can be understood that in this embodiment, the mechanical movement of the elastic switch 132 is combined with the magnetic attraction connection between the first connecting member 131 and the second connecting member. When the plug 52 is inserted, it will first abut against and press the elastic switch 132, causing it to switch from one state to another. In different states of the elastic switch 132, the telescopic length of the elastic switch 132 in the direction of the plug 52 is different, resulting in a change in the relative position between the second connecting member (located on the plug 52) and the first connecting member 131 (located inside the charger), thereby controlling the magnetic attraction connection or disconnection between them. Specifically, when the plug 52 is received in the plug receiving groove 13, the elastic switch 132 is in the first state. At this time, the second connecting member approaches the first connecting member 131, and the plug 52 is firmly fixed in the plug receiving groove 13 by magnetic attraction connection; when the user needs to take out the plug 52, the plug 52 can be pressed towards the plug receiving groove 13. At this time, the bottom of the plug 52 will press the elastic switch 132. As the plug 52 presses and continues to insert the elastic switch 132, the elastic switch 132 switches from the first state to the second state, so that the telescopic length of the elastic switch 132 in the direction of the plug 52 becomes longer, and the relative position between the second connecting member and the first connecting member 131 changes, causing the magnetic attraction connection between them to be disconnected, and the portion of the plug 52 close to the wire body 51 passes through the plug receiving groove 13 and is exposed. The user can grasp the exposed portion and pull out the plug 52 from the plug receiving groove 13. It should be explained that the elastic switch 132 belongs to the prior art and can be referred to but not limited to the elastic pressing portion on a ballpoint pen, which will not be elaborated here.

[0047] Optionally, the housing 1 is rectangular, the hidden groove 11 is provided on the upper side or the lower side of the housing 1, and the wire receiving groove 12, the connection hole 14, and the plug receiving groove 13 are provided on the horizontal outer periphery of the housing 1.

[0048] Compared with the prior art, for the charger with a hidden storage plug of the present utility model, by designing a hidden groove, the plug can be completely folded and stored therein, improving the overall aesthetics of the charger; at the same time, with the elastic member cooperating with the pop-up button, the unlocking lever and the locking member, the user only needs to press the pop-up button, and through the interaction of the unlocking lever and the locking member, the automatic pop-up of the plug can be realized without manually pulling out the plug, and the operation is simple and convenient.

[0049] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
